Student Exploration: Period of a Pendulum Vocabulary : controlled experiment, mean, pendulum, period Federalism, mode of political organization that unites separate states or other polities within an overarching political system in a way that allows each to maintain its own integrity . Federal systems do this by requiring that basic policies be made and implemented through negotiation in some form, so that all the members can share in making and executing decisions.

Student Exploration: Natural Selection Vocabulary:biological evolution, camouflage, Industrial Revolution, lichen, morph, natural selection, peppered moth Prior Knowledge Questions (Do these BEFORE using the Gizmo.) The peppered moth (Biston betularia) is a common moth found in Europe, Asia, and North America. It is commonly found in two forms, or morphs: a dark morph and a light, speckled morph. Birds are a frequent predator of the peppered moth. 1. Which morph do you think would be eas...

The image shows a single litter of kittens. How are they similar to one another? All of them are kittens, have a white belly, have spots of color throughout their body, and seem to have no missing body parts. 2. H...

Student Exploration: Mineral Identification Vocabulary: crystal, density, hardness, homogeneous, luster, mass, mineral, streak, volume Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. Suppose you find a yellow piece of metal in a stream. How could you tell if it is real gold? The real gold would not be magnetic, while fake gold would be. 2.

Suppose the feather color of a bird is controlled by two alleles, D and d. The D allele results in dark feathers, while the d allele results in lighter feathers. 1. Suppose two Dd birds mate. What percentages of DD, Dd, and dd offspring would you predict? Use th...

Activity: Moles, Avogadro, and Molar Mass Prior Knowledge Questions 1. In the image, note a dozen eggs, a dozen donuts and a dozen roses. How many of each item do you have? 12 eggs, 12 donuts, and 12 roses. 2. Would a dozen of each object have the same mass? No 3. Suppose you have a dozen silver atoms, a dozen oxygen atoms, and a dozen lithium atoms. Even though you have the same number of each, will they all have the same mass? Explain. They will not all have the same mass because altho...
